Nursing Elites

1. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?

• A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
• B. Administer a retention enema of Kayexalate.
• C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
• D. Administer a lidocaine bolus IV push.

Correct answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.

2. When obtaining an admission history for a client who is at 9 weeks gestation, the client states, 'I had a miscarriage 2 years ago.' Which information is most important for the nurse to obtain?

• A. How long was your previous pregnancy?
• B. How long did it take for you to become pregnant after your miscarriage?
• C. Was your miscarriage during the first trimester?
• D. Do you have any children now?

Correct answer: A

Rationale: The correct answer is A. Understanding the duration of the previous pregnancy helps assess the client's obstetric history. Choice B focuses on the time it took to conceive after the miscarriage, which is less relevant at this point. Choice C asks about the timing of the miscarriage rather than the duration of the previous pregnancy. Choice D inquires about the current status of having children, which is not directly related to the client's obstetric history.

3. A client who is 12-hours post-op following a left hip replacement has an indwelling urinary catheter. The nurse determines that the client's urinary output is 60 ml in the past 3 hours. What action should the nurse take first?

• A. Assess the client's vital signs
• B. Irrigate the catheter with 30 ml of sterile normal saline
• C. Notify the healthcare provider
• D. Replace the catheter with a larger size

Correct answer: A

Rationale: In a client post-op with low urinary output, the first action the nurse should take is to assess the client's vital signs. Vital signs can provide valuable information about the client's overall condition, fluid status, and potential complications. Assessing the vital signs can help the nurse to determine if the low urine output is indicative of a larger issue that needs immediate attention. Irrigating the catheter with normal saline may be necessary but should not be the first action without assessing the client. Notifying the healthcare provider should follow assessment if there are concerns. Replacing the catheter with a larger size is not indicated solely based on low urinary output and should not be the first action taken.

4. The nurse is assessing on the first postoperative day following thyroid surgery. Which laboratory value is most important for the nurse to monitor?

• A. Calcium
• B. Sodium
• C. Chloride
• D. Potassium

Correct answer: A

Rationale: Corrected Rationale: Monitoring calcium levels is crucial post-thyroid surgery to detect hypocalcemia, a common complication due to injury or removal of the parathyroid glands. Monitoring sodium, chloride, or potassium levels is not as vital in the immediate post-thyroid surgery period.

5. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.
